Background: Soil Fungi play a vital role in maintaining the soil health. Such Microbial communities offer stability and greater yield in agro-ecosystems. The current study was aimed to evaluate the diversity of rhizospheric fungi present in the Banana plantation site and estimate the values of the selected physico-chemical parameters of the soil.Methods: Soil samples were collected from the two selected sites i.e. Site MK and Site ZB, from Nagaland State, India During the month of October 2019. Soil temperatures, pH, Moisture, organic carbon and Available Nitrogen were measured by standard protocols. Fungi were isolated in Potato dextrose agar and Rose agar plates following serial dilution method. Plates were incubated at 25±1°C for 5-7 days. Fungal colonies were observed and transferred to appropriate identification media and identified with the help of literature.Result: A total of 19 different fungal isolates were recorded from the two sites. It was observed that the Genus Aspergillus was dominant in both the sites.

Physicochemical Characterisation

Petroleum hydrocarbons are a critical environmental contaminant and pose a serious hazard to the living system as petroleum hydrocarbons are identified as carcinogenic and neurotoxic organic pollutants. Therefore, remedial methods are required to dispose of it. With a modern understanding of nature and microorganisms, bioremediation is the preferred method for soil pollution control. However, before the implementation of successful bioremediation technology, it is required to assess various physico-chemical parameters of contaminated soil. In the present study, various physico-chemical parameters, including pH, electrical conductivity, water holding capacity, organic carbon, organic matter, available nitrogen, carbonate, bicarbonate, potassium and sodium contents of the petroleum hydrocarbon contaminated soil were estimated. The results suggested a rise in all the estimated parameters for the petroleum hydrocarbon-contaminated soil.

Soil fungi represent one of the important microbial groups that are actively involved in enhancement of environmental quality and plant nutrient supply. Studying native soil fungal species and their accurate identification is crucial for contribution to the checklist of fungi. The present study aimed at isolation and identification of some soil fungi from Jhum land, Mokokchung district, Nagaland. Serial dilution method was used to isolate soil fungi on RBA (Rose Bengal Agar) and PDA (Potato Dextrose Agar) plates. Altogether fourteen fungal species belonging to genera Absidia, Alternaria, Aspergillus, Cladosporium, Fusarium, Geotrichum, Mortierella, Mucor, Penicillium and Trichoderma were identified by studying their macro- and micro-morphological characteristics.

The lemongrass (Cymbopogon citratus L.) essential oil plays a vital role as an ingredient in different fields due to aromatic, antibacterial properties and antifungal activity. In this study, essential oil of lemongrass was obtained using hydrodistillation method and evaluated for chemical compositions and physico-chemical characteristics. The averaged physico-chemical parameters were determined as specific gravity (0.8865 g/cm3), acid index (2.948), ester index (6.402) and refractive index (9.35). Moreover, the hydrodistillation process performance was achieved 0.29%. The composition of essential oils was analyzed by GC-MS, revealing a total of 18 volatile constituents existing in the lemongrass oil. The major components were α-citral (40.838%), β-citral (28.494%), β-myrcene (16.654%), 2,3-dehydro-1,8-cineole (2.264%) and geraniol (2.388%). The citral component accounts for high content (more than 70% of volume) of oil.

Abstract Through the Visual Encounter Survey only one species of green frog (Euphlyctis hexadactylus) was encountered. As we lack previous data we cannot comment on the decline of the species. Frogs, known for specific habitats, are under threats if such habitats are lost. The physico-chemical parameters estimated along with the anuran survey reported that the quality of the lake is not congenial to support the tadpoles of the frogs. The adults can move away from water and survive on land. The habitat, as well as the surrounding wetland, plays a vital role to support a good quantum of anurans.
